Fix Win32SurfaceKHR::getSurfaceCapabilities asserting when hwnd is no longer valid

When vkGetPhysicalDeviceSurfaceCapabilitiesKHR is called, we now return VK_ERROR_SURFACE_LOST_KHR on Windows if the window handle (hwnd) is no longer valid. The assert was being tripped by Chromium's compositor_unittests for test LayerWithRealCompositorTest.BackgroundBlur. With this fix, instead of an assert, the test now fails because eglQuerySurface fails with EGL_BAD_SURFACE.
